Hitunglah nilai dari a. P(4,3) c. P(11,7) b. P(6,3) d.

a. 24, b. 120, c. 1.663.200, d. 24.024

Pembahasan

Perkalian permutasi P(n, k) dihitung dengan rumus P(n, k) = n! / (n-k)!, di mana "!" menunjukkan faktorial.

a. P(4,3) = 4! / (4-3)! = 4! / 1! = (4 × 3 × 2 × 1) / 1 = 24
b. P(6,3) = 6! / (6-3)! = 6! / 3! = (6 × 5 × 4 × 3 × 2 × 1) / (3 × 2 × 1) = 6 × 5 × 4 = 120
c. P(11,7) = 11! / (11-7)! = 11! / 4! = 11 × 10 × 9 × 8 × 7 × 6 × 5 = 1.663.200
d. P(14,4) = 14! / (14-4)! = 14! / 10! = 14 × 13 × 12 × 11 = 24.024
